T 0- all whom it may concern: v

Be it known that l, LIGE ROBISON, citizen of the United States, residing at Four States, in the county of Marion and State of West Virginia, have invented certain new and useful Improvements in Artificial Goal, of which the following is a specification.

This invention relates to new and useful improvement-s in fuel and has reference particularly to that type of fuel manufactured in lump or brick form from various miscellaneous ingredients all of which are essential to fuel for producing the maximum heat in the absence of coal.

The substitute coal consists of the following ingredients in the proportions named for making approximately a ton of the fuel;

Paper or pasteboard, 400 pounds,

Coke dust, 800 pounds,

Sawdust, 350 pounds,

Slack coal, 400 pounds,

Soda, 5 pounds,

00d alcohol, 5 gallons,

Coal oil, 4 gallons.

The paper or pasteboard or any other suitable waste material of similar characteristics provide a binder for the fuel when mixed with the other ingredients. The coke dust forms a fuel as does the sawdust. The slack coal when pulverized to a dust and mixed with the other ingredients forms a tar and also assists in binding the various ingredients together. From the soda, the fuel is caused to burn brighter and has the tendency of decreasing the amount of soot from the fuel. The wood alcohol is used as a smoke destroyer together with the soda and also has the effect upon the coal of re ducing the amount of soot emanating therefrom. The common coal oil has the effect of causing the fuel to ignite rapidly.

Application filed August 30, 1821.

Serial No. 496,962.

To mix the various ingredients, the paper or pasteboard, is ground into almost a powder and the slack coal is crushed into practically dust. All of the ingredients are then mixed together in the proportions mentioned and sufficient water is added to the mixture to make it possible to mix the compound into a stiff dough. This mixture 1S then placed into small molds and permitted to dry out after which the blocks are removed and ready to be used as fuel.

The use of the fuel has proven that it will not be consumed by the fire rapidly, and will ive out a great amount of heat without giving off a great amount of soot and smoke. The substitute coal has also been found to be practically entirely consumed by the fire thereby leaving very little waste in the form of ashes.

Having thus fully described my invention, I claim:

1. A substitute fuel comprising pulverized paper, finely crushed coal, soda, wood alcohol, and coal oil.

2. A substitute fuel comprising pulverized paper, pulverized coke, sawdust, slack coal, soda, wood alcohol, and coal oil.

3. A substitute coal consisting of the following ingredients in about the proportions named, pulverized paper e00 pounds, coke dust, 800 pounds; finely crushed slack coal 00 pounds, sawdust 350 pounds, coal oil 4: gallons, alcohol 5 gallons, and soda 5 pounds.

In testimony whereof I afiix my signature in presence of two witnesses.
